6 Claims. (Cl. 221-92) This invention relates to selective vending machines wherein a number of articles to be vended, usually of different characteristics, are normally disposed in a vending position locked against removal and having for its primary object the provision of structure permitting the removal of but one article during each cycle of operation of the machine.

It is the purpose of this invention to provide a selective vending machine permitting a customer to choose from a number of articles the one which he desires to purchase, but including novel captive mechanism for preventing the customer from removing more than one article each time a coin is deposited and a selected article removed.

It is the most important object of the present invention to provide a vending machine particularly adapted to handle bottled beverages and including a plurality of inclined shelves for bottles containing differing beverages, there being mechanism permitting the removal of a single bottle from any selected shelf but preventing the customer from removing additional bottles during a single cycle of operation commencing with the insertion of a coin or like medium. 7

Another object hereof is to provide a vending machine wherein the aforesaid shelves are inclined for feeding the bottles automatically to a vending station, the mechanism above mentioned being equipped with a divider shiftable each time the machine is placed in operation to restrain gravitational rolling of the bottles on the shelves and thereby obviating the possibility of removing more than one bottle from a given shelf.

A further important object of the invention hereof is to provide captive mechanism including swingable gates for each shelf respectively, together with latching means automatically looking all remaining gates against swinging movement when any one gate is operated by the customer through removal of a selected bottle.

A still further object is to provide captive mechanism as just above set forth including shiftable linkage movable to a locked position preventing removal of any bottle or other article of merchandise if the purchaser attempts to move two or more gates simultaneously toward an article-releasing position.

Other objects include many details of construction made necessary to carry out the above mentioned primary objects, all of which will be made clear as the specification hereof progresses, reference being had to the accompanying drawings, wherein:

Fig. 11 is an enlarged, fragmentary, cross-sectional view taken on line XI-Xl of Fig. 1 looking in the direction of the arrows.

Any suitable refrigerated cabinet may be employed for housing the mechanism of the present invention including a preferably transparent auxiliary door covering an elongated, vertical outlet slot for clearing the articles to be vended. A housing or cabinet of this character is illustrated in pending application Serial No. 106,548, filed July 25, 1949, in the names of i. E. Hagstrom and E. C. Johnson, and owned by the assignee hereof.

The unit illustrated in the drawings is housedwithin such cabinet and suitably mounted therein with a plurality of vertical outlet openings 29 (Figs. 6 and 7) facing the aforesaid vertical slot of the cabinet. The openings 20 are formed in an elongated, upright panel 22 that is in turn joined with an opposed, rearmost channel member 24 (Figs. 1, 5 and 8) through the medium of a pair of spacers 26 at the uppermost and lowermost ends respectively of the panel and channel member 24, the lowermost spacers 26 only being shown in the drawings (Figs. 1, 6, 7 and 8), i

A receiving station adjacent each opening 20 respectively for articles to be vended illustrated herein as beverage bottles 28, is presented by the medium of an adjustable rack 30 carried by the panel 22 and the channel member 24. Each rack 30 is substantially L-shaped presenting a bottom wall 32 and an upstanding flange 34, an elevated plateau 36 being provided in the bottom wall 32 adjacent the corresponding opening 2% and beneath the neck of the bottles 28 for reasons hereinafter to be made clear.

The racks or cradles 30 are supported adjacent the flange 34 thereof through the mediuin of a pin 38 secured to the bottom wall 32 and/or the flange 34. That end of each pin 38 respectively next adjacent the panel 22 extends into a hole 40 formed in a small bracket 42 that is in turn attached to the inner face of panel 22. The bracket 42 has a plurality of horizontal shoulders 44 selectively received by the pin 38 whereby the angularity of the rack 30 may be adjusted.

The channel member 24 has a pair of opposed flanges 45 and 48 (Fig. 5), flange 45 being provided with shouldered openings (not shown) similar to openings 40 and shoulders 44 in brackets 42 for receiving the opposite end of the pin 38. A second pin 5% supports the rack 3%) at the opposite iongitudinal margin thereof and is preferably threaded through the bottom wall 32 by means of openings 52 formed in the latter. One end of pin 5%) is selectively received by any one of a number of 'spacer 82. e

. i 3 openings 54 in the panel 22and a like number of openings (not shown) in the flange 48 receives the opposite end of pin 50. It is seen therefore, that there is provided a plurality of fbottie-receiving cradles bet'ween'the panel 22 and the channel member 24 in spaced, superimposed relationship.

Thebottom'wall 32 of each rack 30 respectively, has

..a longitudinal ledge 56 along that edge thereof opposite to the upstanding flange 34 for receiving one end of an inclined shelf 58, the superimposed shelves '58 being otherwise supported within the. Cabinet in any suitable manner notshown; A plurality of bottles 28 on each shelf 58 respectively, are free to roll by gravitation to thecorresponding racks 30 and it is obvious that upon removal of a bottle 28 from any one rack 30 in the manner illustrated by Fig. 4 of the drawings, the remaining bottles 28 will roll along shelf 58, thereby positioning another bottle 28 in alignment with an opening 20 as soon as the same comes into contact with the stop flange 34'.

An elongated, vertical strip 60 having the cross-sectional configuration shown by Fig. 11 of the drawings, is secured to the innermostface of the panel 22 adjacent the flanges 34. A U-shaped gate' 62 is provided for each opening 20 respectively. Each gate 62 has a pair of oppositely extending pintles 64 and '66, the pintle 64 being journaled in the strip 60. and there being provided a bracket 68 on the inner face of panel 22 for journaling the pintle 66.

A lateral extension 70 on each pintle 66 respectively, pivotallyreceives'as at 72 one end of an elongated divider 74. A link 76 pivotally mounted within channel A member 24 as at 78 pivotally receives as at 80, the opposite end of the divider bar 7 It is notable at this point thereto and disposed above the corresponding rack 30. 7 A spacer 82 (Fig. 11) is secured to each of the pintles 64 adjacent the outermost face of the strip and an elongated dog 84 is preferably integral with the spacer 82.; Each dog 84 is provided with a pair of inturned lugs 86 and 88, one on each side respectively of .the

The vertical, longitudinal edges of the strip '60 are .formed to present a pair of opposed channel-shaped tracks 90 for receiving and guiding a plurality of stacked, substantially identical plates 92, together with a lowermost master plate 94, and an elongated, vertically recip- -rocable bar 96 within one of the tracks 90 and on the innermost faces of the plates 92. Any suitable means .not' shown maybe provided on the strip 60 adjacent the uppermost end thereof for holding the bar 96 against movement toward-the dogs 84, the lower end of the bar 96 having an elongated, transverse slot 98 that receives a pin 100 on one end of a short link 102 that is pivotally secured to the strip 60 as at 104. The opposite end of the link 102 has a second pin 106 extending through an elongated, horizontal slot 108 in the master plate 94. Bar 96 is additionally provided with a notch 110 in the innermost longitudinal edge thereof for each lug 86 respec tively.

Plates 92 are each provided with a plurality of inturned ears 112 and 114 extending toward the strip 60 for holding the plates 92 spaced from the strip 60, the ears 112 slidably receiving the proximal edge of the bar 96, master plate 94 being likewise provided with guiding ears, and the bar 96 having lugs 115 that ride in the proximal channel 90. The plates 92 are all substantially H-shaped presenting uppermost and lowermost notches 116 and 118, together with uppermost and lowermost shoulders 120 and 122. It is seen that when all of the plates 92 are in the normal position, spacers or hubs 82 for the dogs 84, are within the notches 116 below the uppermost shoulders 120 (see Fig. 1). Under these conditions the lugs 86 are likewise in corresponding notches 116 whereas 4 the lugs 88 are within the notches 118 in overlying en gagement with shoulders 120. V

A spring 124 joins each dog 84 respectively with the strip 60 to yieldably hold the dogs 84 and accordingly, the gates 62 in such norniaL standby condition. The master plate 94 is at the uppermost end of its path of travel and the bar 96 is at the lowermost end of'its path of travel during the normal standby condition. A spring 126 coiled. about the pivot pin 104 and having. one leg thereof bearing against the pin 106, aids in yiel dably holding the aforesaid parts in such standby condition. The lowermost notch 118a of the master plate 94 is appreciably longer than the notches 118 for clearing the pins 100 and 104. Master plate 94 is provided with a U-shaped extension 128 depending therefrom, one leg whereof has an car 130 extending inwardly below the pin 100 and the other leg having a vertically inclined ear 132 adjacent the lowermost end thereof.

A locking assembly having parts disposed within the space defined by the extension 128, is broadly designated 'tor 152 is in turn pivotally secured to the outermost face of the strip 60 below pivot pin 104 by bolt 154. Actuator 152 is provided with an ear 156 that cooperates with theiear 130' in a manner hereinafter set forth.

A bolt 158 having a slot 160 is mounted on the outermost face of strip 60 below slot 148 for reciprocation transversely of the longitudinal axis of strip 60 by means of guide pins 162 secured to strip 60 and passing through slot'160. Bolt 158 has. an upstanding projection 164 traversing slot-148 onone side of the roller 146 and between the strip 60 and the actuator 152, the latter being cutaway on its innermost face to accommodate the exa tension 164. A spring 166 connecting the bolt 158 and the of travel shown in Fig. 1 of the drawings.

Bolt 158 is notched as at 168 to receive an ear 170 on the uppermost end of a vertically reciprocable trigger 172 on the strip 60. Trigger 172 has an inturned ear extending into a slot'174 in the strip 60 for guiding trigger 172 and an outwardly extending stop 176 on the trigger 172 is within the path of travel of the master plate 94. A spring 178 interconnecting the trigger 172 and one of the guide pins 162, holds the trigger 172 biased to the uppermost end of its path of travel in the manner illustrated by Fig. 1 of the drawings. A projection 180 on one end of the bolt 158 is within the path of travel of the car 132 on master plate 94.

Cylinder 136 is provided with a pair of opposed slots 182 at that end thereofopposite' to end wall 138 for receiving a cross pin 184 on a shaft 186 (Fig. 8). Shaft 186 may form a part of a suitable coin mechanism, not shown, mounted on the door of the cabinet and actuated by a customer after deposit of a coin. The cross pin 184 therefore, may move into and out of slots 182 as' the cabinet door is opened and closed during servicing of the machine. A spring 188 interconnecting the cylinder 136and the strip 60 holds cylinder136 biased toward that end of its path of travel shown in Fig. 8 of the drawings. a

will rest within or upon the rack -or cradle 30 in aligncabinet is-loaded by placing bottles. 28 upon the shelves 58, the lowermost bottle 28 of which ment with a corresponding outlet opening'itl and with the necks of the'bottles 28 next adjacent openings 20 between the bights of corresponding gates 60 and plateaus 36. Since the selected'mechanism hereof is adapted to receive virtually any type of ordinary beverage bottle, it is possible to provide a difierent type of beverage for each of the shelves 58.

The customer, after inserting a proper coin or coins to release shaft 186, rotates the latter to in turn rotate cylinder 136 in the direction of the arrow shown in Fig. 9 of the drawings. Cam slot 144 acting on roller 146, causes the latter to move within slot 148 from the position shown in Fig. 1 of the drawings toward the position shown in Fig. 2.

if for any reason the master plate 94 became lodged at the lowermost end of its path of travel during the cycle of operation next preceding, swinging movement of the actuator 152 moves ear 156 against the ear 130 of master plate 94, thereby forcing the latter to the position shown in Figs. 1, 2 and 3. It is seen further that rotation of the shaft 186 in the direction of the arrow shown in Fig. 2 of the drawings, shifts the bolt 158 to the position shown in Pig. 2 of the drawings by virtue of roller 14-5 engaging the upstanding projection 164 on the bolt 158, all against the actions of spring 188 for cylinder 136 and spring 166 for bolt 158. When the bolt 158 has moved to the position shown in Fig. 3 of the drawings, the ear 179 of trigger 172, snaps into the notch 168 by force of the spring 178. Accordingly, when the customer actuated handle on the shaft 186 is released, and after the spring 188 returns the cylinder 136, roller 146 and actuator 152 to the normal position shown in Figs. 1, 2, 3 and 8, bolt 158 is restrained against return to its normal position by virtue of the interlock between bolt 158 and the trigger 172 all as clearly shown by Fig. 3. Such positioning of the bolt 158 clears the ear 132 for downward movement, it being noted in Fig. 1 that the uppermost edge of the bolt 158 is normally beneath the car 132, thereby limiting the extent of downward movement of the master plate 94.

The customer may thereupon open an auxiliary door as aforementioned, closing the outlet openings 20 and make his selection. By grasping the neck of a selected bottle 23, the customer may move such bottle 28 in the direction of the arrows shown in Fig. 4 and pull the same through a corresponding opening 20. Such action swings the gate 62 corresponding to the selected bottle 28, upwardly and forwardly toward the panel 22. Such swinging movement of gate 62 rotates the pintles 64 and 66 and rotation of the latter swings extension 70 downwardly which in turn shifts the divider bar 74 from the position shown in full lines in Fig. 8 to the dotted line position of Pig. 8, as the link 76 swings on pivot pin 78. As shown in Fig. 4 of the drawings such lowered position of the divider bar 74, is below the uppermost plane of the bottles 28, divider bar 74 therefore, functioning to restrain rotational gravitation of bottles 28 along shelf 58 into the rack 30 from which a bottle 28 has been removed.

Rotation of the pintles 64 imparts swinging movement to the corresponding dog 84 to move the latter from the position shown in Fig. 1 of the drawings to that indicated by Fig. 4, and against the action of the corresponding spring 124. As dog 84 swings, its lug 86 moves into a corresponding notch 116 in the bar 96 and also moves against the shoulder 122 thereabove. The lug 88 on the other hand swings downwardly against the shoulder 12d therebelow. It is seen therefore, that all of the plates 92 above the swinging dog 84, shift upwardly and all of the plates 92 including master plate 94, below the swinging dog 84, move downwardly. Downward movement of the master plate 94 shifts the bar 96 upwardly through action of the link 192, bar 96 accordingly moving simultaneously and in unison with the lug 86 which it receives.

Downward movement of the master plate 94 moves the inclined ear 132 against the projection 180 on the bolt 158, shifting the latter slightly to the left viewing Figs. 1 to 4 inclusive. As the master plate 94 continues downwardly, the bight of the extension 128 thereof comes into contact with stop 176 of latch 172, shifting the latter downwardly against the action of spring 178 as shown in Fig. 4 and thereby moving the ear out of the notch 168.

After the bottle 28 has been removed, the gate 62 returns to the normal position shown in Fig. 7 of the drawings by the action of springs 124, 126 and 178. The corresponding dog 84 returns to the normal position shown in Fig. 1, the upper plates 92 slide downwardly, and the lowermost plates 92 and 94 moving upwardly. As plate 94 returns to the normal position, link 102 will pull the bar 96 downwardly and the ear 132 will move out of engagement with the extension 181 As indicated in Fig. 4 of the drawings, bolt 158 will move to a position where notch 168 is out of alignment with ear 179 before the trigger 172 reaches the uppermost end of its path of travel. Accordingly, as soon as ear 132 moves to the position shown in Fig. 1, spring 166 will snap bolt 158 to the normal position and spring 178 will move the trigger 172 to the position where ear 170 thereof engages the bolt 158 to one side of the notch 168. It is also apparent that when the master plate 94 is at the lowermost end of its path of travel, the car 139 will be in the path of travel of the actuator ear 156, thereby preventing rotation of the shaft 186 while a bottle 23 is being removed.

It is now clear that by virtue of the fact that the ear 132 on the master plate 94 normally overlies the bolt 153, none .of the gates 62 can be swung from the position shown in Fig. 7 of the drawings for the reason that the lugs 88 immediately move against the underlying shoulders or edges 12%. Likewise, the extent of swinging movement of the gate 62 inwardly, is limited by the divider bar 74, striking pivot pin 78 and the pintle 66. Even without divider bar '74 forming a part of the .assembly, the gate 62 cannot be swung inwardly because the lugs 86 will move against the bights of notches 116.

When a bottle 28 is within an opening 2.6 as shown in Fig. 4, and the corresponding dog 84 is swung to the inclined position shown in Fig. 4, no other .gate 62 can be actuated for the reason that all plates 92 below the operating dog 84 and plate 94 have moved to a position where the shoulders 122 move against the corresponding lugs 86 and the corresponding bights of the notches 116 moved against the lugs 88. Likewise, the plates 92 above the actuated dog 34 will be in the position shown in Fig. l where the shoulders 124 underlie the corresponding lugs 88. When a given dog 84 is actuated, the links 92 thereabove initially move downwardly by gravity until the actuated dog 84 assumes a horizontal position. Thereupon, the lug 86 of the actuated dog .84 shifts the overlying plates 92 upwardly to their normal position and the lug 88 forces the plates 92 therebelow and/or the master plate 94 downwardly.

In the event it is attempted to remove two or more bottles 28 simultaneously, thereby swinging a plurality of gates 62 toward the released position, the corresponding plurality of dogs 84 will swing only until the same are horizontal. Further swinging movement of any gate 62 is prevented and the operator cannot even remove'one bottle 28. Such lodging is caused by the fact that when two or more lugs 86 engage their corresponding shoulders 122 and when two or more lugs 88 engage corresponding shoulders 126, there can be no separation of the plates 92 to move one group of plates 92 upwardly and the other group of plates 92, together with plate 94, downwardly.

The bar 96 is provided to eliminate any possibility of a customer removing the bottle 28, thereupon holding the corresponding gate 62 in a released position, closing such gate 62 partially and thereupon actuating another gate 62 'position until the bar 96 has moved downwardly sufficiently far to permit other lugs 88 to move into notches 110. Otherwise, the remaining lugs 88 will strike the bar 96below the notches 110 and prevent full opening of their corresponding gates 62. Once two or more lugs 88 are moved into notches 110, the captive mechanism becomes locked when a plurality of dogs 84 move to the horizontal position.

Having thus described the invention what is claimed as new and desired to be secured by Letters Patent is:
